Makhalidwe a aramid fiber

1, zabwino makina katundu

Ulusi wa Aramid ndi mtundu wa polima wosinthika, mphamvu yake yosweka ndi yayikulu kuposa poliyesitala wamba, thonje, nayiloni, ndi zina zambiri, kutalika kwake ndi kokulirapo, chogwirira chake ndi chofewa, ndipo kupota kwake kuli bwino.Itha kupangidwa kukhala ulusi waufupi ndi ulusi wokhala ndi zokana ndi kutalika kosiyanasiyana, zomwe zimatha kupangidwa kukhala nsalu ndi nsalu zosalukidwa ndi kuchuluka kwa ulusi wosiyanasiyana pamakina ambiri ansalu.Pambuyo pomaliza, imatha kukwaniritsa zofunikira za zovala zotetezera m'madera osiyanasiyana.

2. Kutentha kwabwino kwamoto ndi kukana kutentha.

Kuchepetsa oxygen index (LOI) ya aramid fiber ndi yayikulu kuposa 28, chifukwa chake sipitilira kuyaka ikachoka pamoto.Zomwe zimalepheretsa lawi la aramid fiber zimatsimikiziridwa ndi kapangidwe kake kake, chifukwa chake ndi chiwombankhanga chokhazikika chalawi, ndipo mawonekedwe ake oletsa moto sangachepetse kapena kutayika chifukwa cha nthawi yogwiritsira ntchito komanso nthawi yotsuka.Fiber ya Aramid imakhala ndi kukhazikika kwamafuta abwino, imatha kugwiritsidwa ntchito mosalekeza pa 300 ℃, ndipo imatha kukhalabe ndi mphamvu yayikulu pakutentha kwambiri kuposa 380 ℃.Ulusi wa Aramid uli ndi kutentha kwakukulu kowola, ndipo susungunuka kapena kudontha pa kutentha kwakukulu, ndipo umatulutsa mpweya pang'onopang'ono kutentha kukakhala kopitilira 427 ℃.

3. Khola mankhwala katundu

Ulusi wa Aramid umalimbana kwambiri ndi mankhwala ambiri, ma acid okhala ndi kuchuluka kwambiri komanso kukana bwino kwa alkali kutentha.

4. Kukana kwa radiation

Aramid CHIKWANGWANI chili ndi mphamvu yokana ma radiation.Mwachitsanzo, pansi pa kuyatsa kwa nthawi yayitali kwa 1.2 × 10-2 w / in2 cheza cha ultraviolet ndi 1.72 × 108rads gamma ray, mphamvu yake imakhalabe yosasintha.

5. Kukhalitsa

Aramid fiber imakhala ndi kukana kwamphamvu kwambiri komanso kukana kwamankhwala.Pambuyo pa kuchapa maulendo 100, mphamvu yothyoka ya chingwe, riboni kapena nsalu yopangidwa ndi aramid fiber imatha kufikira 85% ya mphamvu zoyambirira.
